Hi, ipv6calc reached now "feature complete" for 0.96.0, would be great if I get some feedback until Thursday, so I can release the version on Friday. Major improvements: use of md5 bundled code will be only used if not available on the system (external md5 is currently only supported via openssl library). Old behavior can be triggered using: --enable-bundled-md5 (and for getopt: --enable-bundled-getopt) ipv6calcweb.cgi was extended for supporting the new outputformat "textkeyvalue", which can be parsed easier in scripts, example: http://ip.bieringer.de/cgi-bin/ipv6calcweb.cgi?format=textkeyvalue ipv6calc binaries can be build using shared libraries internally to save space on disk with configure option: --enable-shared ipv6calc (approx. 170 kB) ipv6loganon (approx. 50 kB) ipv6logstats (approx. 60 kB) ipv6logconv (approx. 50 kB) libipv6calc.so.0.96.0 (approx. 450 kB) libipv6calc_db_wrapper.so.0.96.0 (approx. 1.8 MB) (containing the BuiltIn databases) instead of ipv6calc (non-shared, 1.9 MB) ipv6loganon (approx. 1.9 MB) ipv6logstats (approx. 1.9 MB) ipv6logconv (approx. 1.9 MB) Thank you in advance for any feedback, Peter
